the jewels will trap a bunch of gunk so those may need to be cleaned pretty often. Small water changes more frequently if necessary. They don't like large changes in pH, etc. Kind of like mellow water, but clean. You can remove and keep the cleaner top half to 3/4 of the water and rinse the bottom and jewels (best with treated water, to preserve any BB and biofilm for the shrimp) to get the dirty gunk out and then add back the new water treated always.
You may want to consider removing some of the jewels for more room for the water. And less places for baby shrimp to get trapped. You have air in there right or a filter ?
